Green-Go GGO-SW81 Ethernet Switch

Green-Go GGO-SW81 Ethernet Switch

Green-Go network bridges are used to make connections between two Green-Go intercom networks located on different sites, across the Internet or a private network, creating a single intercom group spread over the two sites or adding remote users. Green-Go Ethernet switches provide power over Ethernet (POE), and have additional features, such as locking Ethercon network connectors, making them more suitable for use in stage and similar environments than switches designed for use in a data centre.

Main points:

• Connect events globally via the Internet or a private network
• Two or four independent streams of bridge interface
• Connect to two or four remote sites
• No loss of speech clarity
• Pass ‘Call’ alert signalling between sites
• Group bridge and user access modes
• Compact desktop or 1U rackmount format

Bridges have four Ethernet ports, two for internal and two for external networks. The internal ones are normally used for connecting to a Green-Go network local to the bridge unit. One of the internal network ports can be used for powering the bridge via POE. Alternatively, the bridge can be powered with an external power supply. The external ports are used for connecting to the Internet or a private network. The bridges should have fixed IP addresses assigned on External networks. These should be chosen from the same range of IP addresses as is used on the local network, but outside the range of any addresses offered by the router or a DHCP server. Care should be taken to avoid using an IP address that is already in use. UDP port forwarding should be set up in a firewall between the Internet or a private network and a bridge in one of the sites.

Each bridge interface stream can be used in one of two modes, group bridge mode or user access mode.
